TOOL FOR FORMING LUGS IN STOVE-COVERS.

SPECIFICATION forming-part of Letters Patent No. 230,475, dated July 27,1880.

I Application filed January 10, 1880.

To all whom it may concern:

Be it known that 1, JAMES S. GOW, of Quincy, in the county of Adams andState of Illinois, have invented an Improvement in Stove-Covers, ofwhich the following is a specification.

This invention relates to certain improvements in the art ofmanufacturing stove-covers, as hereinafter more fully set forth andpointed out in the claim.

Figure 1 represents a perfected stove-cover, provided with the sink andlifter projections flush with the face of the cover. Fig. 2 represents apattern for the same with the sink and without the lifter projections.Fig. 3 is a perspective of the removable punch by means of which thelifter-projections are formed in the sand. Fig. 4 shows a verticalsection through the center of the sink and lifter pro- 20 jections,showing the punch in place in the preparation of the mold for casting.

In the accompanying drawings, A represents a pattern of a stove-coverprovided with a lifter-sink, a, with an opening in each side thereofextending into the face of the cover. This opening is marked 12. Thispattern is molded in the sand in the usual way, and af-- 1761' beingmolded the cope is removed and the i punch B, one on each side, isinserted into the sides of the sink and openings 12. This punch issharpened and provided with a shoulder, c, the same thickness as thecover itself, and fits into the openings b therein, while the sharpenedblade projects into the sink through the openings in the sides thereof,(in the pattern,) thus pressing away the sand down to the face of thecover. The pattern is then removed, the cope replaced, and the castingmade with the lifter-projections flush with the top of the cover, theiron therefor running into the space made by the blades of the punches.

What I claim as my invention is-' The combination of the pattern A,provided with the lifter-sink 0., having all its sides closed, buthaving the openings b for the insertion of the punch, with the punch B,provided with the shoulder 0, having a sharpened edge, substantially asdescribed, and for the purpose set forth.

JAMES S. GOW.
